GEMU 638电动2/2通道全通径隔膜阀配有一个AUMA制造的电机/控制单元。
功能
可选的橡胶衬里适用于涉及的应用
颗粒介质，例如：
- 采矿
- 脱硫植物
- 纸和木浆工业
- 水处理
- 陶瓷行业
- 化学和染料工业
阀体和隔膜有各种材料和设计
•电动执行器可用于开/关和调节
职责，包括各种控制单位。
•无需辅助气压
优点
•机械稳定性高
•由于直通流动而导致高流速
•可选的流向
•无需拆卸执行器即可清洁阀门
•经过验证的电动执行器和控制单元采用模块化设计
工作介质
腐蚀性，惰性，液体和液体介质，对隔膜和隔膜材料的物理和化学性质没有负面影响。
所有压力均为表压。 通过施加在关闭阀的一侧上的静态操作压力来确定操作压力值。 对于给定值，确保阀座处的密封和大气密封。
根据要求提供双面和高纯度介质的商业压力信息。
Kv值确定为acc。 根据DIN EN 60534，入口压力5 bar，Δp1bar，阀体铸铁EN-GJL-250和法兰EN1092长度EN 558系列7和软弹性体隔膜。
其他产品配置（例如其他隔膜或主体材料）的Kv值可能不同。 通常，所有隔膜都受到压力，温度，过程及其紧固扭矩的影响。Kv值可能超过标准的公差极限。
阀门不适合真空应用
